Definitions

  • the present invention relates to a solar-energy and rainwater collection apparatus and, more particularly but not necessarily exclusively, to a portable, modular apparatus for collecting solar-energy and rainwater. It is known to collect water and solar-energy in combined apparatus. Such devices are commonly used in both commercial and domestic applications.
  • a modular solar-energy and rainwater collection apparatus comprising: a collector mount adapted both for securement to a building and to an angularly-adjustable support; a plurality of rainwater collectors supportable by the collector mount, each rainwater collector having a base, and at least one solar-cell retainer, for securing at least one solar cell relative to the base of at least one said rainwater collector; and connection means, for rigidly interconnecting a plurality of like rainwater collectors so that the bases are in abutted liquid communication with each other thus forming a modular rainwater collection area.
  • the modular solar-energy and rainwater collection apparatus is advantageous as an easily transportable modular system that collects both solar energy and rainwater.
  • the modularity of the apparatus means that the apparatus is easily configurable to meet the requirements of the user, yet both efficient and compact.
  • the apparatus beneficially provides the benefits of existing structures, notably, the ability to both collect rainwater and generate power from solar energy, whilst having the capability to use the generated power to heat the collected rainwater.
  • connection means may advantageously include at least one bridging infill element which interconnects at least parts of neighbouring side walls of two abutted rainwater collectors.
  • the bridging infill element may be a planar or substantially planar member having a first bridging connector part at each end portion of the planar member for engaging complementary second bridging connector parts on the neighbouring side walls of abutted rainwater collectors.
  • the infill elements assist with the modularity of the device. Any number of like rainwater collectors may be interconnected by the bridging infill elements, thereby enabling the modular solar-energy and rainwater collection apparatus to be configurable to the requirements of the user.
  • the modular solar-energy and rainwater collection apparatus may further comprise at least one corner infill element.
  • each corner infill element may have a first wall connector part at each end portion of the corner infill element for engaging complementary second wall connector parts on the discontinuous upstanding perimeter side wall of each rainwater collector.
  • the at least one bridging infill element and/or the at least one corner infill element may complete a perimeter boundary of the modular rainwater collection area.
  • the corner infill elements may define the vertices of the modular solar-energy and rainwater collection apparatus.
  • the corner infill elements are advantageous in that, once the size and orientation of the modular solar-energy and rainwater collection apparatus is determined by the user, the or each bridging infill element, together with the or each corner infill element, may complete a perimeter boundary of the modular rainwater collection area, and may therefore assist in preventing or limiting any rainwater collected from unintentionally escaping.
  • At least one said bridging infill element or corner infill element may include a discharge aperture for the discharge of runoff precipitation accumulated on the modular rainwater collection area.
  • each rainwater collector may form a tray, each tray having a continuous base for the or each associated solar cell to lie thereon.
  • the modular rainwater collection area may be a perimeter gutter with side walls.
  • each rainwater collector may include at least one solar-cell support for supporting the or each solar cell in a spaced apart relationship with the base of an associated rainwater collector.
  • this provides that the or each solar cell is not in contact with the base of an associated rainwater collector and consequently, not in communication with the rainwater collection area, allowing for a greater area to be utilised for the collection of precipitation and preventing any overflow of liquid back on to the surface of the solar cell.
  • the solar-cell retainer may be a solar-cell frame, overlapping the or each associated solar-cell and engageable with the base of the rainwater collector.
  • an upper surface of the solar-cell retainer includes an inwardly-directed slope for runoff precipitation onto an associated solar cell.
  • the solar-cell retainer may include a filter for filtering rainwater running from the or each associated solar cell to the modular rainwater collection area.
  • the filter may prevent or limit debris from passing to the modular rainwater collection area.
  • the filter may be a castellated edge of the solar-cell retainer.
  • any precipitation is directed onto an associated solar cell, from which it will pass through a filter to the modular rainwater collection area.
  • Including a filter assists in preventing or limiting debris flowing to the modular rainwater collection area and assists in preventing sediment building up and clogging the apparatus.
  • precipitation directed onto an upper surface of the solar cell advantageously assists with self-cleaning of the solar cell.
  • an upper surface of the solar-cell retainer may include at least one conduit mount for positively engaging at least one liquid conduit.
  • each conduit mount may include two conduit retainers for positively engaging two liquid conduits in side-by-side relationship, the conduit mount extending laterally between an inner perimeter sidewall and an outer perimeter sidewall of the solar-cell retainer.
  • at least one liquid conduit may be supported by the rainwater collectors.
  • the or each said liquid conduit may be positively engaged with the or each solar-cell retainer.
  • this provides that the or each liquid conduit may thereby be positively supported by the liquid conduit mounts in side by side relationship on the solar-cell retainer.
  • the modular solar-energy and rainwater collection apparatus may further comprise a rainwater accumulator for storing accumulated runoff rainwater discharged from the modular rainwater collection area.
  • the or each liquid conduit may be in liquid communication with the rainwater accumulator, and include pump means adapted to pump runoff rainwater from the rainwater accumulator through the liquid conduit.
  • the modular solar-energy and rainwater collection apparatus may include a heated-water reservoir for receiving runoff rainwater which is heated when pumped through the liquid conduit supported by the rainwater collectors.
  • this system provides that runoff rainwater collected in the modular rainwater collection area may be circulated in the or each liquid conduit.
  • runoff rainwater may then be heated by solar energy before being received by the heated-water reservoir.
  • the modular solar-energy and rainwater collection apparatus may further comprise an electricity supply for powering the apparatus.
  • the modular solar-energy and rainwater collection apparatus may further include a UV purification device arranged to purify the rainwater collected by the apparatus by UV radiation.
  • the electricity supply may supplement the or each solar cell converting solar power into electricity and assist with the operation of the pump, enabling the apparatus to be used to circulate and heat runoff rainwater even when solar energy is not available.
  • the UV purification device permits the runoff rainwater to be treated and assists in killing bacteria in the runoff rainwater.
  • the angularly-adjustable support may have first and second elements, the first element being adapted to engage the collector mount, and the second element being adapted for mounting on a support surface.
  • the first and second elements may be frames.
  • the first and second elements may also be hingeably interconnected.
  • the first and second elements may be adapted to house one or both of the rainwater accumulator and heated-water reservoir, between the first and second elements.
  • the apparatus can be mounted on the angularly-adjustable support with the frame being adaptable to house one or both of a rainwater accumulator and a heated-water reservoir. Therefore, the apparatus can be deployed to any location and can be used in disaster areas or where temporary relief is required.
  • the angularly-adjustable support is beneficial in making the device more adaptable than existing solutions as no sloped or pitched surface is required, due to the support being capable of providing the required pitch or angle.
  • a modular solar-energy and rainwater collection apparatus comprising: a collector mount adapted both for securement to a building and to an angularly-adjustable support; at least one solar cell for collecting solar energy; and a plurality of rainwater collectors supportable by the collector mount, each rainwater collector having: a base; and at least one solar-cell retainer, for securing at least one solar cell relative to the base of at least one said rainwater collector; and connection means for rigidly interconnecting a plurality of like rainwater collectors so that the bases are in abutted liquid communication with each other thus forming a modular rainwater collection area.
